Hello Ian,
My name is Alex and I have seen your website and I wished to know if
you could help me ...!
I have a "CIRSE 8mm SOUND PROJECTOR - 24 FPS (1957)" and I have repaired and restored it but now I have a little problem:
after a thorough internal revision, I found a thread that has isconnected
(yellow wire) I do not understand where it can go (ground wire ..?). I'm trying to find the original electric diagram.....
Thank you very much for your attention and for all the help that you can give me!
Alex
Here is a photograph of the Cirse amplifier:
REPLY: You must not work on an amplifier when connected to the mains! The old capacitors may explode if suddenly connected up after 50 years!
Hello Alex,
I am pleased that you found my description of the Cirse 8mm projector
helpful.
I no longer have the Cirse. It was 20 years ago and I cannot remember the wiring as the amplifier was working so I did not work on it.
The wire will have broken off at a solder joint and there may be a mark and frayed wire as evidence where the yellow wire was joined. A close look with a magnifying glass under a strong light may show where it broke away from. Often, the wire will have taken up a shape that points to the region where it was attached.
From your photographs it is not possible to tell where the yellow wire goes on the circuit.
If the yellow wire comes from a transformer? then you can check the
resistance readings of the tappings with an Ohmeter which will identify its
purpose. There is usually a diagram printed on the transformer cover showing
the tappings.
I know a technician who has a Cirse and I will post him your photographs of the amplifier. He may be able to help.
